Example:
myEnumerable.Select(a => ThisMethodMayThrowExceptions(a)); How to make it work even if it throws exceptions? Like a try catch block with a default value case an exceptions is thrown...

C# exception handling is built upon four keywords: try, catch, finally, and throw. try − A try block identifies a block of code for which particular exceptions is activated. It is followed by one or more catch blocks.
How to make use of both Take and Skip operator together in LINQ C#? The Take operator is used to return a given number of elements from an array and the Skip operator skips over a specified number of elements from an array. Skip, skips elements up to a specified position starting from the first element in a sequence.
The order of catch statements is important. Put catch blocks targeted to specific exceptions before a general exception catch block or the compiler might issue an error. The proper catch block is determined by matching the type of the exception to the name of the exception specified in the catch block.
LINQ offers common syntax for querying any type of data source; for example, you can query an XML document in the same way as you query a SQL database, an ADO.NET dataset, an in-memory collection, or any other remote or local data source that you have chosen to connect to and access by using LINQ.
myEnumerable.Select(a => { try { return ThisMethodMayThrowExceptions(a)); } catch(Exception) { return defaultValue; } }); But actually, it has some smell.
About the lambda syntax:
x => x.something is kind of a shortcut and could be written as
(x) => { return x.something; } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
